Hard disks, solid state drives
Raid on different disks. Is it worth it?
Recently I took a 2 Maxtor to create a mirrored Raid. Just put all, as one of the discs fly (there bedy). Accept the guarantee can be said that the same or a different order. Here I think there is now a similar take, or order another. Who has any opinions there are on this matter? Or for a Raid-1 is better to identical drives with the same parameters?
I would not recommend Maxtor generally put.
What would you advise?
I want to put myself in a pair in a RAID 1: Seagate 7200. 9 + Hitachi KLSA80
e. OK, that they are different, with different characteristics? Although Maxtor positions this model as a "disc with increased resiliency." And 30 months warranty pleases. And the Hitachi (at least for us) is always year warranty (gray type of delivery).
My logic is this: the two screws at the same time is unlikely to lay a warranty of 2, 5 years there. . .
It all depends on what kind of raid and why. If it is 0 or 5, then, of course, for maximum performance is better to put the same Hardy and backup. If you want cheap storage increased reliability, t. E. The 1st level, it makes sense to put Hardy different manufacturers . Using different components they (CDM) will have different uptime and under normal conditions is not immediately kick the bucket. For RAID5 vseravno backup taxis, and for especially 0.
Different in terms of better protection of designers errors.
